Which of the following State has suffered a dilution of the tribal share of population due to industrialisation?

Jharkhand

The correct answer is Option (1) → Jharkhand

Many tribal concentration regions and states have also been experiencing the problem of heavy in-migration of non-tribals in response to the pressures of development. This threatens to disrupt and overwhelm tribal communities and cultures, besides accelerating the process of exploitation of tribals. The industrial areas of Jharkhand for example have suffered a dilution of the tribal share of population. But the most dramatic cases are probably in the North-East. A state like Tripura had the tribal share of its population halved within a single decade, reducing them to a minority. Similar pressure is being felt by Arunachal Pradesh.
